TORIPEDO.

-Application filed November 5, 1923. Serial No. 672,975.

This invention relates to improvements in torpedoes and more particularly to one of the transverse bulkheads separating the after-body from the midship section,

` One of the objects of the present invention is to provide a bulkhead especially adapted to withstand the pressure in'th'e immersion chamber generated by the impulse charge.

A further object is to provide an improved bulkhead with stiffening and reinforcing parts more efficiently supportingthe engine and taking up the thrust of the enine.

g A further object is to provide a bulkhead of the above general character of relatively light construction, extremely strong and adapted to fully withstand the various end strains exerted thereon.

Other objects will be in part obvious and in part hereinafter pointed out in connection with the accompanying sheets of drawings illustrating one of the various possible embodiments of the invention and wherein similar parts are indicated by corresponding reference characters.

In these drawings, Figure 1 is a rear elevat-ional view showing such parts of the entire bulkhead as are necessary to fully understand the same.

Figure 2 is a side elevation thereof, and,

Figures 3 and 4 are two types of reinforcement either of which may be used in duplicate.

Referring now to the drawings in detail, 5 indicates the rim of the bulkhead which is positioned transversely in the `torpedo just forward of the engine and aft of aI combustion flask indicated at 6. This bulkhead is provided with a forwardly bulging part 7 adapted to accommodate the turbine wheels, the vertical shaft of which passes through openings 8 in the upper and lower struts'as shown in Figures 3 and 4. rIhese struts 10 and 11 are of general triangular shape cut away as indicated at 12 to reduce weight as muchas possible. The ends 13 of both struts are connected by a vertically disposed brace 14 which also acts as a Support for the propeller shafts extending rearwardly fromthe turbine shafts. It will also be noted that theV bulkhead is provided with vertically disposed struts 15 adjacent each side of the shaft and having its ends tied to the turbine frame whereby the load is more effectively distributed and transferred to adjacent parts. The central part of the bulkhead is extensively ribbed, as indicated at.16, to fully withstand the end thrust'J exerted lthereon by the propeller shafts. Various openings and parts 17 are provided as may be necessary through which are adapted to pass the pipes or other conduits for transmitting the air or fuel used for driving the turbines.

It will thus be seen that the present in' vention provides a strong and suitable bulkhead fully adapted to accomplish, among others, all of the objects and advantages herein set forth.

What I claim is 1. A torpedo bulkhead comprising a circular disk, upper and lower directly turbine supporting frames connected to the disk and extending from one side thereof beyond the turbine, and means connecting the outer ends of said frames.

2. A torpedo bulkhead comprising a circular disk, upper and lower turbine supporting frames directly connected to the diskand extending from one side thereof beyond the turbine, and a forwardly extending bulging portion adapted to accommodate the y turbine.

3. A torpedo bulkhead comprising a. circular disk, an upper and a lower turbine supporting plateextending from one side thereof beyond the turbine, said upper and lower turbine supporting plates being connected'by vertically disposed girders at each side of the center.

4. A torpedo bulkhead comprising a cir cular disk, and upper and lower turbine supporting plates directly connected to the i disk and extending from one .side thereof, said upper and lower plates being connected' at their ends by a vertically disposed bearing member for the propeller shafts.

5. A torpedo bulkhead comprising a circular disk, upper and lower turbine Supporting plates extending therefrom, said disk being provided with reinforcing strengthening ribs positioned transversely and diagonally across the disk between said plates.

6. A torpedo bulkhead comprising a eir- K cular disk, upper and lower `strengthening members extending therefrom, said meinbers supporting a turbine shaft, and tie-rods connecting the inner and outer ends of the strengthening members, one of the tie rods l0 supporting the propeller sha-Lft.v y
